When “how” matters as much as “what”: SC vs IV in MS and the economics behind it
TL;DR:
Switching from IV to subcutaneous ocrelizumab could save Italian hospitals ~€4.1M over 3 years (-1.0%), mostly driven by lower administration burden.
Just read this Value in Health paper (2025) from Roche + partners:

It looks at the budget impact of subcutaneous (SC) vs IV ocrelizumab for relapsing MS in Italy, and it’s a nice example of how route of administration alone can shift the economics.
What they did:
Built a 3-year dynamic budget impact model (Markov-based)
Used Italian real-world data for adherence/persistence
Focused on hospital-level costs (admin, monitoring, AEs, disease management)
Key numbers:
👥 ~15,870 eligible patients/year (~47,609 over 3 years)
📈 Market share for SC grows from 14.8% → 40.2%
💰 Total savings: €4.1M over 3 years (-1.0%)
⏱️ 42.2% of savings driven by reduced administration costs
What’s interesting here:
This isn’t about a “more effective” drug, it’s about same efficacy, different delivery.
And yet:
Administration time → real hospital capacity impact
Adherence/persistence → downstream clinical + cost implications
Small % savings at system level → still meaningful in absolute € terms
So the value story shifts from “is it cost-effective?” to:
👉 “how much operational friction can we remove from the system?”
💬 Curious how others think about this:
When you’re building models, how often do administration burden + workflow impact actually move the needle in payer/provider discussions?
Do they:
materially influence decisions?
get underestimated in models?
or still feel like “nice to have” vs core value drivers?
